One other significant correlation for this - Pierre attributes the 'Eureka moment' of his understanding of Aikido not to his japanese teachers ..but to Chinese scholars quoting Tchang Sai for instance "Everything in the universe is made of Qi" and from the Ling Tchou (a book on medicine) "the living being must not be considered as matter animated by the spirit, it is energy that directs matter, itself a form of energy, towards the phenomum of life"

Heavy stuff...but still consistent with the source of Dans teachings that Aiki predates O'sensei.
